Input files total up to 1 GiB. The video must contain an audio track. Exports are limited to 24 hours.
How to use this tool
- Upload a video with audio and let the preview prepare.
- Choose the track, time range and MP3 bitrate.
- Preview, export and download the audio.
Settings and results
Select the audio track you need and optionally trim its time range. Higher MP3 bitrates create larger files and cannot restore missing detail from the original audio.
File storage and deletion
Files are uploaded and processed on the server. Originals and results are stored privately and accessed through their account or browser session; downloads use short-lived links. By default, files expire 24 hours after upload and are removed by the cleanup process. You can delete them earlier in your workspace. The current local default allowance is 20 uploaded files per 24 hours.

Can I extract audio from a silent video?
A video without an audio track cannot produce MP3 audio. This tool extracts existing sound; it does not generate speech or music.
